CVE-2026-46312

In the Linux kernel, the following vulnerability has been resolved: media: videobuf2: Set vmaflags in vb2dmasgmmap vb2dmacontig sets VMA flags VMDONTEXPAND and VMDONTDUMP and I do not see a reason why vb2dmasg should behave differently. This avoids hitting WARNON!vma-vmflags & VMDONTEXPAND; in...

CVE-2026-46312

The CVE-2026-46312 vulnerability in the Linux kernel concerns media: videobuf2. A fix was applied to vb2_dma_sg_mmap to set VMA flags (VM_DONTEXPAND/VM_DONTDUMP) so that vb2_dma_sg behaves consistently with vb2_dma_contig. This change prevents a WARN_ON in drm_gem_mmap_obj() during mmap() of an i...
